Patented Apr. 28, 1931 UNITE a STATES HER-Beard.' margins, or connessi/funn: vrnarrmal TIRE-GAUGE HOLDER.`

Application' filed April 4,

The present invention is directed to improvements in holders for tire pressure gauges.

The primary object of the invention is to provide a device of this character'in which a tire gauge can be placed and maintained in such position that the same can be con-l veniently used, yet can not be removed from the holder.

A further object of the invention is to provide a device of this character so constructed that it will forma part of the supply hose in order to prevent patrons of filling stations or garages taking the gauge.

It frequently occurs that a patronof a filling station will borrow the tire gauge from an attendant and after inflating the tires will thoughtlessly carry the gauge away, which entails quite a loss to filling stations, and it is to overcome this objection that the holder has been perfected.V

While the drawing illustrates a preferred embodiment of the invention it is to be understood that in adapting the means to meet specific needs and requirements the design may be varied and changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention vand the merits thereof, reference is to be had to the following description and the drawing hereto attached, in which,

Figure lis a side elevation of the device.

Figure 2 is a longitudinal sectional view.

Corresponding and like parts are referred to in the following description and designated in the views of the drawing by like reference characters. A

The holder 1 comprisestubular sections 2 and 3, the section 3 being closed at one end by a head 4, said head carryinga threaded stem 5 which projects into the section 3 and has an air passage 5 therein in order that air from the hose 6 may pass into the stem. The stem has formed therein a valve seat 7 and cooperating with said seat is a valve 7, the

stem 8 of which projects slightly beyond the inner end of the stem 5.

finger, the barrel will slide inwardly and cause thenipple 21 to engage and push the disk 15, thus causing the pin 14 to unseat thefvalve 7 whereupon rair entering the section 3 will pass through the tube 23 and head 24 intothe tire valve. Air is permitted Vto flowinto the tire until it is desired to obtain a reading, whereupon the button 27 is released and the Vforefinger removed from the member;19 whereupon the pressure built up in the tire will back up into thesection 3, and against the washer 2O to slide the washer and gauge forward. The valve 7 the disk 15 and the intermediate parts will follow the movement of the washer under the influenceV of the spring 9 and the'air pressure on'the disk until the stop 30 onthe .pin 14: mpinges against the guide 13, whereupon the washer will `move forward from the disk under the air pressure. The nipple will be freed from the disk, as shown in Fig. 2, and the compressed air will flow into the .gauge to operate-the sameV in thel usual manner. VIt will be noted thatthev gauge is slidable l.as anen- Atirety in .the holder .and operates as a pis'- ton to open the valve 7 the outward movement .of the-gauge barrel 17 `being limited by the flange thereon engaging .the inner end of the section 2 ofthe holder. If the reading is not correct or the tire is: underlnflated the gauge fis again forcedy back in the tubularbody to unseat the valve 7 and permit an additional supply of air Vto flow into the tire. y 5 Y I Ahave illustrated `the tube 23 as being a rigid part of the holder, but by minor changes a short length of rubber hose may fbe substituted therefor in order that the device may v be' more conveniently. used when inating tires upon disk wheels. Y'

Aholder of the class described will permit tires to be inflated and the pressure registered in a much shorter quired. l p

Having Ythus ldescribed the invention, I claim:

A holder comprising a tubular body'having an'inletand an .outlet for air under pressure, a pressure gauge slidablyhoused in thebody, a valve for controlling the flow throughqthe inlet, yieldable means fory holdl time than now re- Y'
